MECHANICALLY-WORKED PLOW.

SPECIFICATION forming part of Letters Patent No. 764,445, dated J uly 5, 1904.

Application iled June 15, 1903. Serial No. 161,594. (No model.)

T0 a/Z, whom vt mfG/y con/cern.-

Be it known that we, ROBERT HENRY Fow- LER, engineer, THoMAs BENs'iEAD, draftsman, and ALFRED PEPPER, engineer, all of Steam Plow Works, Leeds, in the county oi' York, England, have invented certain new and useful Improvements in Mechanically -Worked Plows, of which the following is a specilieation, for which l have applied for a patent in Great Britain, dated January 30, 1903, No. 2,303.

This invention relates to improvements in the construction of standards adapted primarily to be used on mechanically-worked plows to secure strength, side stiffness, and lightness, and also provides means for the ready and accurate adjustment of the shares on such plows to suit the requirements of working different kinds of soil.

In the accompanying drawings, Figure l is an elevation showing the improved construction of standard which forms one part of the present invention; and Fig. 2 is a part section on line 2 2 of Fig. 1, showing the method oi' attaching the standard to the main frame ot' the plow.

Referring to Figs. l and 2, the plow-stand;n ard consists of a plate a, preferably corrugated or iianged, o'r both, or otherwise reinforced by strengthening-ribs, except at its lower end, where the surface is left iiat for the reception of the frog Z, which has a corresponding flat face at its Lipper part and to which the share and moldboard are attached in the usual manner. The body is lixed to the main frame c, which is preferably of channel section, by stirrup-bolts (l or other suitable means and to the frog by a pivot-bolt e and one or more elamijiing-bolts f, which latter pass through segmental slots f in the frog. The adjustment is eliected by a screwed bolt g, pivoted on a pin or bolt g', iixed to the body and passing through an eye (f2 in ,thc skiie, to which it is lixed by nuts y on either side of the eye.

Having thus described the nature of this invention and the best means we know oi carrying the same into practical efl'ect, we claim- The combination of a plow-standard, the upper part of'which is corrugated and the lower portion 0i' which is flattened, a frog correspondingly flattened to iit against the l'lat portion oi the standard, said frog having a projection at its rear, a bolt having an eye at its upper end, the threaded portion oi' the bolt extending through a perforation in said pro jection, nuts upon the threaded portion of the bolt at opposite sides of the projection, a pin passing through said eye, carried by the standard, a pivot uniting the standard and frog, said two last-mentioned parts having registering perforations to receive said pivot, and clamping-bolts passing through openings in the standard and lfrog respectively, one open ing in each case being elongated, and the respective openings and perforations being triangularly arranged.

1n witnesswhereof we have hereunto set our hands in presence oli' two subscribing witnesses.
